The type of epithelial cells which line the inner surface of Fallopian tubes, bronchioles and small bronchi are known as

Options

A. squamous epithelium
B. columnar epithelium
C. cillated epithelium
D. cubical epithelium

Answer

To answer the question regarding the type of epithelial cells that line the inner surface of the Fallopian tubes, bronchioles, and small bronchi, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Epithelial Tissue**:
- Epithelial tissue is a type of tissue that forms the outer layer of organs and structures throughout the body. It serves various functions, including protection, absorption, and secretion.

2. **Types of Epithelial Cells**:
- Epithelial cells can be classified based on their shape and arrangement. The main types include:
- **Squamous Epithelium**: Flat and thin cells.
- **Cuboidal Epithelium**: Cube-shaped cells.
- **Columnar Epithelium**: Taller, column-like cells.

3. **Identifying the Specific Type**:
- The question specifies that we are looking for epithelial cells that line the inner surfaces of specific organs: the Fallopian tubes, bronchioles, and small bronchi.

4. **Ciliated Epithelium**:
- Among the types of epithelial cells, the ones that are often found in the respiratory tract (like bronchioles and small bronchi) and reproductive tract (like Fallopian tubes) are typically **ciliated epithelial cells**.
- Ciliated epithelium can be either cuboidal or columnar in shape, and it has tiny hair-like structures called cilia on their surface.

5. **Conclusion**:
- Therefore, the type of epithelial cells that line the inner surface of the Fallopian tubes, bronchioles, and small bronchi are known as **ciliated columnar epithelium**.

### Final Answer:
The epithelial cells lining the inner surface of Fallopian tubes, bronchioles, and small bronchi are known as **ciliated columnar epithelium**.
